Abstract
The present invention describes a process for preparing ultrapure (≧95%) galacto-oligosaccharides (GOS), starting from GOS at lower purities by using sequential microbiological purifications involving Saccharomyces cerevisiae and Streptococcus thermophilus.
Claims9
A process for preparing GOS mixtures with a purity 95% in which the overall percentage of the digestible sugars lactose, glucose and galactose is ≦5%, starting from GOS mixtures of a lower purity, said process comprising one fermentation step with Streptococcus thermophilus and at least one fermentation step with Saccharomyces cerevisiae, where said purity is calculated by any analytical method able to distinguish and quantify GOS and said digestible sugars.
GOS mixtures with a purity ≧95% wherein galacto-disaccharides other than lactose are present in quantities ≧1% and the overall percentage of the digestible sugars lactose, glucose and galactose is ≦5%.
